CVE-2024-48948 (GCVE-0-2024-48948)

Vulnerability from cvelistv5 – Published: 2024-10-15 00:00 – Updated: 2025-11-25 15:41
VLAI
Summary
The Elliptic package 6.5.7 for Node.js, in its for ECDSA implementation, does not correctly verify valid signatures if the hash contains at least four leading 0 bytes and when the order of the elliptic curve's base point is smaller than the hash, because of an _truncateToN anomaly. This leads to valid signatures being rejected. Legitimate transactions or communications may be incorrectly flagged as invalid.
Severity
